Hi All,
I have spherical coordinates (right ascension, declination) and I’d like to iterate over areas in this 2-dimensional space. Easiest that comes to mind is just create a grid of squares (say 5 arcsecs wide) and iterate over them.
Is it easier to do this in MonetDB with just spherical coordinates (some kind of spherical index), or do I have to convert them to x,y,z coordinates and create the grid in 3D?
Thank you for your insight.
